The System boot files signified by the System flag have been moved from the System partition to F which I assume is your External backup and which we cannot even see on the drive map. This is incorrect and problematic.
You'll need to boot into Windows 7 DVD, press Shift + F10 at first screen to access a Command Line and use Diskpart to mark F Inactive: Partition - Mark as Inactive - Windows 7 Forums
Then power down and unplug F so that it won't interfere as the System Boot files are rewritten to System partition, which is marked Active thus ready to receive them.
Boot into the Windows 7 DVD Repair console on second screen or System Repair Disk
to run Startup Repair - Run 3 Separate Times
until Windows 7 starts. Confirm System partition now holds the System flag.
Next plug back in F, move the data off to wipe it using Diskpart Clean Command
from an Elevated Command Prompt
so that all traces of the boot loader are removed from it.
There should never be any Active partitions except for System which should be in Disk0 position to avoid moving boot files during repairs.
